If you’re new to computers, or just want to brush up on your skills, this is the post for you! We’ll cover all the basics, from turning on your machine to using basic applications. By the end of this post, you’ll have a good understanding of how your computer works and be able to use it for everyday tasks.

Let’s start with the very basics – turning on your computer. For most machines, you’ll need to press and hold down the power button for a few seconds. Once it’s turned on, you should see some type of initial screen that gives you information about your machine – this is called the BIOS screen.

From here, you can usually press a key (like F2 or Esc) to enter into BIOS Setup mode, or let the computer boot up normally into its operating system. Assuming you’re booting up normally, what happens next depends on which operating system (OS) your machine is running. If it’s Windows 10 , 8 , or 7 , chances are good that you’ll see a login screen where you can enter your username and password.

On Mac OS X , however, your computer will automatically log in as the admin user; if there’s more than one user set up on the machine, then you’ll see a list of users and can select yours from there. Once logged in, you should see something called the desktop – this is basically your home base when using your computer.

Definition of Computer for Class 1

In computing, a computer is a device that stores and processes data according to instructions provided by a software program. It can be used for a wide range of purposes, including task automation, information processing, and communication. Computers come in many different shapes and sizes, from large mainframe computers to small handheld devices.

They can be classified by their size, power, functionality, and application. Mainframe computers are the most powerful type of computer; they are used for large-scale applications such as weather forecasting or airline reservations. Desktop computers are less powerful than mainframes but more versatile; they are commonly used in offices for word processing and spreadsheets.

Laptop computers are portable versions of desktop computers; they typically have less storage capacity and processing power than their desktop counterparts but are still suitable for basic computing tasks. Smartphones and tablets are smaller still and designed for portability and convenience; they typically have limited storage capacity and processing power but offer access to a wide range of applications via the internet.


A computer is an electronic device that stores and processes information according to instructions. It can be programmed to perform a wide variety of tasks, from simple calculations to complex operations. A computer is composed of hardware, which includes the processor, memory, storage, and input/output devices, and software, which refers to the programs that tell the hardware what to do.
